Abstract
The apparatus for preventing a secondary accident by short of sensing lines in a high voltage battery using a fuse, includes: a plurality of battery modules provided with a plurality of battery cells; a battery pack including a plurality of battery modules; a battery management system (BMS) for monitoring and controlling voltage of each battery cell provided in each battery pack to monitor the status of each battery cell; sensing lines connected between the battery module and the battery management system to sense voltage of each battery cell of each battery pack; and a passive safety device to be connected in series to a terminal of each battery cell provided in each battery pack when a short accident that a closed circuit is formed in the sensing line occurs.
